Description

CROSS-REFERENCE TO RELATED APPLICATIONS
This application claims priority to Korean Application No. 10-2007-0113310, filed on Nov. 7, 2007, the disclosure of which is incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a carpet for a vehicle and a method of manufacturing the same.
2. Description of the Related Art
A vehicle typically has a sound absorbing material installed on a dash panel, which separates the engine room from the passenger compartment, to absorb the sound generated in the engine room, and on the floor panel, to absorb sound transmitted through the floor panel from the outside.
The sound absorbing material is generally made of polyethylene terephthalate (PET), which is a good sound absorber as well as a thermal insulator, on the floor panel, PET felt is usually used.
The sound absorbing material is interposed between the floor panel and the carpet. A seat rail is mounted in a seat rail slot, defined in the sound absorbing material and in the carpet.
PET is soft, and compresses when pressure is applied thereto. This is a particular problem if pressure is applied to the carpet on both sides of the seat rail slot: since the strength is compromised near the seat rail slot, the carpet markedly sinks.
The information disclosed in this Background of the Invention section is only for enhancement of understanding of the background of the invention and should not be taken as an acknowledgement or any form of suggestion that this information forms the prior art that is already known to a person skilled in the art.
SUMMARY OF THE INVENTION
Disclosed are a carpet for a vehicle and a method of manufacturing the same. A first material is scored to define a gap. A portion of the first material interior to the gap is compressed, and then folded out of the gap. A second material is adhered to the first material.
The second material may be adhered to the compressed portion of the first material. The volume of the compressed portion may be decreased by about half. The first material may be a sound-absorbing material.
BRIEF DESCRIPTION OF THE DRAWINGS
The above and other features of the present invention will now be described in detail with reference to certain exemplary embodiments thereof illustrated the accompanying drawings which are given hereinbelow by way of illustration, and thus are not limitative of the present invention, and wherein:
FIG. 1 is a cross-sectional view illustrating a sound absorbing material piece being scored and compressed to form a carpet for a vehicle in accordance with an embodiment of the present invention;
FIG. 2 is a cross-sectional view illustrating the carpet of FIG. 1 mounted to a floor panel; and
FIG. 3 is a flow chart of a method of manufacturing a carpet for a vehicle in accordance with another embodiment of the present invention.
It should be understood that the appended drawings are not necessarily to scale, presenting a somewhat simplified representation of various preferred features illustrative of the basic principles of the invention. The specific design features of the present invention as disclosed herein, including, for example, specific dimensions, orientations, locations, and shapes, will be determined in part by the particular intended application and use environment.
In the figures, reference numbers refer to the same or equivalent parts of the present invention throughout the several figures of the drawing.
DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Reference will now be made in detail to preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings and described below. While the invention will be described in conjunction with exemplary embodiments, it should be understood that the description is not intended to limit the invention to the exemplary embodiments. On the contrary, the invention is intended to cover not only the exemplary embodiments, but also various alternatives, modifications, equivalents and other embodiments, which may be included within the spirit and scope of the invention as defined by the appended claims.
Referring to FIGS. 1 and 2, a carpet for a vehicle in accordance with an embodiment of the present invention comprises a sound absorbing material 100 attached to the upper surface of the floor panel 400 of a vehicle, and a carpet material 200 which is attached to the upper surface of the sound absorbing material 100.
The sound absorbing material 100 may function to reduce the noise and vibrations transmitted through the floor panel 400, and may be made of polyethylene terephthalate (PET) felt. The sound absorbing material 100 has a gap or other discontinuity 111 defined therein, such as a seat rail slot, in which a seat rail 300 is mounted.
The sound absorbing material 100 includes a main portion, or main sound absorbing material, 110; and a compressed portion, or sound absorbing material piece, 120.
In the embodiment illustrated in FIG. 1, the sound absorbing material piece 120 is scored or trimmed from the sound absorbing material 100, compressed, and then folded to the configuration shown in FIG. 2. It is preferred that the sound absorbing material piece 120 be compressed so that its volume is decreased by half.
When the sound absorbing material piece 120 is compressed, the volume decreases by half but the weight does not change; therefore the density increases. As a result, the strength of the sound absorbing material 100 near the sound absorbing material piece 120 is attached, is reinforced.
Referring to FIG. 3, in a method for manufacturing a carpet for a vehicle according to an embodiment of the present invention, the sound absorbing material 100 including the main sound absorbing material 110 and the compressed sound absorbing material piece 120 is formed such as by using a mold. Then, after the compressed sound absorbing material piece 120 is trimmed from the slot 111 defined in the sound absorbing material 100, the main sound absorbing material 110 and the compressed sound absorbing material piece 120 are integrally molded together with the carpet material 200, whereby the manufacture of the carpet for a vehicle is completed.
As is apparent from the above description, embodiments of the present invention provide a durable carpet with low manufacturing cost.
Although preferred embodiments of the present invention have been described for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as defined in the accompanying claims.
